Re: Cyanotype, please tell me when your done?
BTW, I wash my cyanotypes by changing water at least 3 times (it's not a good idea to not change the water) and I don't over wash (10 minutes max.). Washing time depends on paper; thin papers need shorter washing times, thick papers longer. 2009/8/21 Loris Medici <mail@loris.medici.name>: > Jacek, put about 5-10ml (per 1000ml) 3% hydrogen peroxide into the > last clearing bath to instantly oxidize the print....
